BACKGROUND Field of Disclosure

The present disclosure generally relates to electric driven hydraulicfracking systems and specifically to a single Variable Frequency Drive(VFD), a single shaft electric motor, and a single hydraulic pumppositioned on a single pump trailer.

Related Art

Conventional hydraulic fracking systems are diesel powered in thatseveral different diesel engines apply the power to the hydraulic pumpsas well as several types of auxiliary systems that assist the hydraulicpumps to execute the fracking, such as hydraulic coolers and lube pumps.Conventional diesel powered hydraulic fracking systems require a dieselengine and a transmission to be connected to a hydraulic pump to drivethe hydraulic pump. However, typically several hydraulic pumps arerequired at a single fracking site to prepare the well for the laterextraction of the fluid, such as hydrocarbons, from the existing well.Thus, each of the several hydraulic pumps positioned at a singlefracking site require a single diesel engine and single transmission toadequately drive the corresponding hydraulic pump requiring severaldiesel engines and transmissions to also be positioned at the singlefracking site in addition to the several hydraulic pumps.

Typically, the diesel engines limit the horsepower (HP) that thehydraulic pumps may operate thereby requiring an increased quantity ofhydraulic pumps to attain the required HP necessary prepare the well forthe later extraction of fluid, such as hydrocarbons, from the existingwell. Any increase in the power rating of hydraulic pumps also resultsin an increase in the power rating of diesel engines and transmissionsrequired at the fracking site as each hydraulic pump requires asufficiently rated diesel engine and transmission. As the dieselengines, transmissions, and hydraulic pumps for a single fracking siteincrease, so does quantity of trailers required to transport andposition configurations at the fracking site.

The numerous diesel engines, transmissions, and hydraulic pumps requiredat a fracking site significantly drives up the cost of the frackingoperation. Each of the numerous trailers required to transport andposition configurations require CDL drivers to operate as well asincreased manpower to rig the increased assets positioned at thefracking site and may be classified as loads in need of permits, thusadding expense and possible delays. The amount of diesel fuel requiredto power the numerous diesel engines to drive the numerous hydraulicpumps required to prepare the well for the later extraction of thefluid, such as hydrocarbons, from the existing well also significantlydrives up the cost of the fracking operation. Further, the parasiticlosses typically occur as the diesel engines drive the hydraulic pumpsas well as drive the auxiliary systems. Such parasitic losses actuallydecrease the amount of HP that is available for the hydraulic pumpsoperate thereby significantly decreasing the productivity of hydraulicpumps. In doing so, the duration of the fracking operation is extendedresulting in significant increases in the cost of the frackingoperation. The diesel engines also significantly increase the noiselevels of the fracking operation and may have difficulty operatingwithin required air quality limits.

System Overview

FIG. 1 illustrates a top-elevational view of a hydraulic frackingoperation such that the hydraulic pumps may pump a fracking media into awell to execute a fracking operation to extract a fluid from the well. Ahydraulic fracking operation 100 includes a fracking trailer 170 that afracking configuration may be deployed. The fracking configuration maybe the fracking equipment that executes the actual fracking to preparethe well for the later extraction of the fluid from the well. Forexample, the fracking trailer 170 may include the fracking equipmentthat implements the missile as well as the well heads that are affixedonto the well and distribute the fracking media into the well to preparethe well for later extraction of the fluid from the well. The fluidextracted from the well may include a liquid, such as crude oil, and soon, or a gas, such as such as hydrocarbons, natural gas and so on, thatis extracted from the well that is then stored and distributed.

The power that is generated to provide power to each of the numerouscomponents included in the hydraulic fracking operation 100 ispositioned on a power generation system 110. Often times, the frackingsite is a remote site where it has been determined that sufficient fluidhas been located underground to justify temporarily establishing thehydraulic fracking operation 100 for a period of time to drill the welland extract the fluid from the well. Such fracking sites are often timespositioned in remote locations such as uninhabited areas in mountainousregions with limited road access to the fracking sites such that thehydraulic fracking operation 100 is often times a mobile operation whereeach of the components are positioned on trailers that are then hauledto the fracking site via semi-trucks and/or tractors. For example, thefracking trailer 170 includes the fracking equipment which is hauled invia a semi-truck and is positioned closest to the well as compared tothe other components in order to execute the fracking operation.

In another example, the power generation system 110 may also be a mobileoperation such that the power generation equipment may be mounted on apower generation trailer and transported to the fracking site via asemi-truck and/or tractor. The power generation system 110 may bepositioned on the fracking site such that any component of the hydraulicfracking operation 100 may be powered by the power generation system110. In doing so, the power required for the hydraulic frackingoperation 100 may be consolidated to the power generation system 110such that the power generation system 110 provides the necessary powerrequired for the hydraulic fracking operation 100. Thus, the powergeneration system 110 may be positioned at the fracking site in a mannersuch that each component of the hydraulic fracking operation 100 mayhave power distributed from the power generation system 110 to eachrespective component of the hydraulic fracking operation 100.

The power generation system 110 may include power generation systemsthat generate electric power such that the hydraulic fracking operation100 is powered via electric power generated by the power generationsystem 110 and does not require subsidiary power generation systems suchas subsidiary power generation systems that include diesel engines. Indoing so, the power generation system 110 may provide electric power toeach component of the hydraulic fracking operation 100 such that thehydraulic fracking operation 100 is solely powered by electric powergenerated by the power generation system 110. The power generationsystem 110 may consolidate the electric power that is generated for theelectric driven hydraulic fracking system 100 such that the quantity andsize of power sources included in the power generation system 110 isdecreased.

The power sources are included in the power generation system 110 andoutput electric power such that the electric power outputted from eachpower source included in the power generation system 110 is collectivelyaccumulated to be electric power at a power generation voltage level aswill be discussed in detail below. For example, the power output foreach of the power sources included in the power generation system 110may be paralleled to generate the electric power at the power generationvoltage level. The power generation system 110 may include numerouspower sources as well as different power sources and any combinationthereof. For example, the power generation system may include powersources that include a quantity of gas turbine engines. In anotherexample, the power generation system 110 may include a power source thatincludes an electric power plant that independently generates electricpower for an electric utility grid. In another example, the powergeneration system 110 may include a combination of gas turbine enginesand an electric power plant. The power generation system 110 maygenerate the electric power at a power level and a voltage level.

The power generation system 110 may generate electric power at a powergeneration voltage level in which the power generation voltage level isthe voltage level that the power generation system is capable ofgenerating the electric power. For example, the power generation system110 when the power sources of the power generation system 110 include aquantity of gas turbine engines may generate the electric power at thepower generation voltage level of 13.8 kV which is a typical voltagelevel for electric power generated by gas turbine engines. In anotherexample, the power generation system 110 when the power sources of thepower generation system include an electric power plan may generate theelectric power at the power generation voltage level of 12.47 kV whichis a typical voltage level for electric power generated by an electricpower plant.

In another example, the power generation system 110 may generateelectric power that is already at a VFD voltage level to power thesingle shaft electric motor 150(a-n) as discussed in detail below. Insuch an example, the power generation system 110 may generate theelectric power that is already at the VFD voltage level of 4160V. Inanother example, the power generation system 110 may generate theelectric power at the power generation voltage level at a range of 4160Vto 15 kV. In another example, the power generation system 110 maygenerate electric power at the power generation voltage level of up to38 kV. The power generation system 110 may generate the electric powerat any power generation voltage level that is provided by the powersources included in the power generation system 110 that will beapparent to those skilled in the relevant art(s) without departing fromthe spirit and scope of the disclosure. The power generation system 110may then provide the electric power at the power generation voltagelevel to the power distribution trailer 120 via a medium voltage cable.

In an embodiment, the power generation system 110 may generate electricpower at a power level of at least 24 Mega Watts (MW) that is generatedat a power generation voltage level of at least 13.8 kV. In anotherembodiment, the power generation system 110 may generate electric powerat a power level of at least 24 MW that is generated at a powergeneration voltage level of at least 12.47 kW. The power generationsystem 110 may generate electric power at a power level such that thereis sufficient electric power to adequately power each of the componentsof the hydraulic fracking operation 100 while having gas turbine enginesin quantity and in size that enable the gas turbine engines to betransported to the fracking site and set up remotely via a trailer. Indoing so, the power distribution trailer 110 may include gas turbineengines that generate sufficient electric power to adequately power eachof the components of the hydraulic fracking operation 100 while notrequiring a large quantity of gas turbine engines and gas turbineengines of significant size that may significantly increase thedifficulty and the cost to transport the gas turbine engines to thefracking site.

In order to provide sufficient electric power to adequately power eachof the components of the hydraulic fracking operation 100 while notrequiring large quantities of gas turbine engines and/or gas turbineengines of significant size, the power distribution trailer 110 mayinclude single or multiple gas turbine engines that generate electricpower at power levels of 5 MW, 12 MW, 16 MW, 20-25 MW, 30 MW and/or anyother wattage level that may not require large quantities of gas turbineengines and/or gas turbine engines of significant size that will beapparent to those skilled in the relevant art(s) without departing fromthe spirit and scope of the disclosure. In another example, the powergeneration system 110 may be the electric utility power plant that islocal to the location of the fracking operation such that the powerdistribution trailer 120 may receive the electric power at the powerlevel of 24 MW and the power generation voltage level of 12.47 kVdirectly from the electric utility power plant.

In an embodiment, the power generation system 110 may include a firstgas turbine engine that generates electric power at a first power levelin range of 12 MW to 16 MW and a second gas turbine engine thatgenerates electric power at a second power level in a range of 12 MW to16 MW. The first gas turbine engine and the second gas turbine enginegenerate the same voltage level of at least 13.8 kV that is provided toa power distribution trailer 120 when the first power level is in therange of 12 MW to 16 MW generated by the first gas turbine engine iscombined with the second power level in the range of 12 MW to 16 MW. Inorder to provide sufficient electric power to adequately power eachcomponent of the hydraulic fracking operation 100 as well as limit thequantity of gas turbine engines as well as the size of the gas turbineengines such that the gas turbine engines may be positioned on a singletrailer and transported to the fracking site, the power generationsystem 110 may include two electric gas turbine engines that generateelectric power at power levels in the range of 12 MW to 16 MW such thatthe electric powers at the power levels in the range of 12 MW to 16 MWmay be paralleled together to generate the total electric power that isavailable to power each of the components of the hydraulic frackingoperation 100 is in the range of 24 MW to 32 MW.

Further, the power generation system 110 including more than one gasturbine engine to generate the electric power provides redundancy in thepower generation for the hydraulic fracking operation 100. In doing so,the power generation system 110 provides a redundancy to the electricdriven hydraulic fracking system in that the first gas turbine enginecontinues to provide the first power level to the power distributiontrailer 120 when the second gas turbine engine suffers a short circuitand/or other shutdown condition and the second gas turbine enginecontinues to provide the second power level to the power distributiontrailer 120 when the first gas turbine engine suffers the short circuitand/or other shutdown condition. The power generation system 110 maythen maintain a reduced quantity of hydraulic pump(s) 160(a-n) tocontinuously operate in the continuous duty cycle without interruptionin continuously pumping the fracking media due to the redundancyprovided by the first gas turbine engine and the second gas turbineengine.

By incorporating two gas turbine engines that generate electric power atpower levels in the range of 12 MW to 16 MW redundancy may be providedin that the electric power that is provided to the components of thehydraulic fracking operation 100 such that the fracking media iscontinuously pumped into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the welldespite one of the gas turbine engines suffering a short circuitcondition. In doing so, the incident energy at the point where the shortcircuit occurs may be reduced due to the reduced short circuitavailability of the power generation system 110. However, if one of thegas turbine engines were to fail due to a short circuit condition, theremaining gas turbine engine may continue to provide sufficient power toensure the fracking media is continuously pumped into the well. Afailure to continuously pump the fracking media into the well may resultin the sand, which is a major component of the fracking media coming outof the suspension and creating a plug at the bottom of the well whichtypically results in a significant expense to remove the sand in thewell so that the fracking can continue. The power generation system 110may include any combination of gas turbine engines and/or single gasturbine engine at any power level to sufficiently generate electricpower to adequately power each of the components of the hydraulicfracking operation 100 that will be apparent to those skilled in therelevant art(s) without departing from the spirit and scope of thedisclosure.

The power generation system 110 may generate the electric power at apower generation voltage level that is in the medium voltage range of1.0 kilo Volts (kV) to 72.0 kV. However, in an embodiment, the powergeneration system 110 may generate the electric power at the powergeneration voltage level of 13.8 kV. In another embodiment, the powergeneration system 110 may generate the electric power at the powergeneration voltage level of 13.8 kV. The generation of the electricpower at the voltage level in the medium voltage range enables mediumvoltage cables to be used to connect the power generation system 110 tothe power distribution trailer 120 to propagate the electric power fromthe power generation system 110 to the power distribution trailer 120 aswell as enabling the use of medium voltage cables to propagate theelectric voltage level to any of the components powered by the electricpower in the medium voltage range. The use of medium voltage cablesrather than the use of low voltage cables decreases the size of thecable required in that medium voltage cables require less copper thanlow voltage cables thereby reducing the size and/or quantity of thecables required for the distribution of power throughout the hydraulicfracking operation 100.

Further, the consolidation of gas turbine engines to decrease thequantity of gas turbine engines required to power the components of thehydraulic fracking operation 100 and/or the incorporation of theelectric utility power plant also consolidates the quantity of mediumvoltage cables that are required to connect each of the gas turbineengines to the power distribution trailer 120 thereby further reducingthe cost of the cables required for the hydraulic fracking operation100. Further, the power generation system 110 generated the electricpower at the power generation voltage level of 13.8 kV and/or 12.47 kVenables the hydraulic fracking operation 100 to be more easilyintegrated with any electric utility grid anywhere in the world suchthat the electric utility grid may be more easily substituted into thepower generation system 110 in replacement of the gas turbine enginessince it is more common that the electric utility grid has transformersavailable to deliver the electric power at the power generation voltagelevel of 13.8 kV and/or 12.47 kV.

The power distribution trailer 120 may distribute the electric power atthe power level generated by the power generation system 110 to eachvariable frequency drive (VFD) 140(a-n) positioned on each pump trailer130(a-n). As noted above, the power generation system 110 may include atleast one gas turbine engine, the electric utility grid, and/or acombination thereof, to generate the electric power. In doing so, amedium voltage power cable may be connected from each component of thepower generation system 110 to the power distribution trailer 120. Forexample, the power generation system 110 may include two gas turbineengines with each of the gas turbine engines generating electric powerat the power level of 12 MW to 16 MW at the voltage level of 13.8 kV. Insuch an example, two medium voltage cables may then connect each of thetwo gas turbine engines to the power distribution trailer 120 such thatthe electric power at the power level of 12 MW to 16 MW at the voltagelevel of 13.8 kV may propagate from the gas turbine engines to the powerdistribution trailer 120.

The power distribution trailer 120 may then distribute the electricpower to each of the VFDs 140(a-n) positioned on each of the pumptrailers 130(a-n). As will be discussed in detail below, severaldifferent hydraulic pumps 160(a-n) may be required to continuously pumpthe fracking media into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the well. Indoing so, each of the different hydraulic pumps 160(a-n) may be drivenby a corresponding VFD 140(a-n) also positioned on the correspondingpump trailer 130(a-n) with the hydraulic pump 160(a-n). Each of the VFDs140(a-n) may then provide the appropriate power to drive each of thesingle shaft electric motors 150(a-n) that then drive each of thehydraulic pumps 160(a-n) to continuously pump the fracking media intothe well to execute the fracking operation to prepare the well for thelater extraction of the fluid from the well. Thus, the powerdistribution trailer 120 may distribute the electric power generated bythe power distribution trailer 110 which is consolidated to reduce thequantity of the gas turbine engines to the several different VFDs140(a-n) positioned on each of the pump trailers 130(a-n). Thecomponents of the power distribution trailer 120 may be transported tothe fracking site.

For example, the power distribution trailer 120 is configured todistribute the electric power at the power level of at least 24 MWgenerated by the at least one gas turbine engine from the voltage levelof at least 13.8 kV to the single VFD 140 a positioned on the singlepump trailer 130 a. In such an example, the power generation system 110includes two different gas turbine engines that generate the electricpower at the power level of 12 MW to 16 MW and at the voltage level of13.8 kV. Two different medium voltage cables may then propagate theelectric power generated by each of the two gas turbine engines at thepower level of 12 MW to 16 MW and at the voltage level of 13.8 kV to thepower distribution trailer 120. The power distribution trailer 120 maythen combine the power levels of 12 MW to 16 MW generated by each of thetwo gas turbine engines to generate a power level of 24 MW to 32 MW atthe voltage level of 13.8 kV. The power distribution trailer 120 maythen distribute the electric power at the voltage level of 13.8 kV toeach of eight different VFDs 140(a-n) via eight different medium voltagecables that propagate the electric power at the voltage level of 13.8 kVfrom the power distribution trailer 120 to each of the eight differentVFDs 140(a-n). The power distribution trailer 120 may distribute thepower generated by any quantity of gas turbine engines to any quantityof VFDs that will be apparent to those skilled in the relevant art(s)without departing from the spirit and scope of the disclosure.

In an embodiment, the power distribution trailer 120 may include aplurality of switch gear modules in that each switch gear moduleswitches the electric power generated by each of the components of thepower generation system 110 and received by the corresponding mediumvoltage cable to the medium voltage cable on and off to each of thecorresponding VFDs 140(a-n). For example, the power distribution trailer120 may include eight different switch gear modules to independentlyswitch the electric power generated by the two gas turbine engines atthe medium voltage level of 13.8 kV as received by the two differentmedium voltage cables on and off to the eight different medium voltagecables for each of the eight corresponding VFDs 140(a-n) to distributethe electric power at the medium voltage level of 13.8 kV to each of theeight corresponding VFDs 140(a-n).

In such an embodiment, the switch gear modules may include a solid stateinsulated switch gear (2SIS) that is manufactured by ABB and/orSchneider Electric. Such medium voltage switch gears may be sealedand/or shielded such that there is no exposure to live medium voltagecomponents. Often times the fracking site generates an immense amount ofdust and debris so removing any environmental exposure to live mediumvoltage components as provided by the 2SIS gear may decrease themaintenance required for the 2SIS. Further, the 2SIS may be permanentlyset to distribute the electric power from each of the gas turbineengines to each of the different VFDs 140(a-n) with little maintenance.The power distribution trailer 120 may incorporate any type of switchgear and/or switch gear configuration to adequately distribute theelectric power from the power generation system 110 to each of thedifferent VFDs 140(a-n) that will be apparent to those skilled in therelevant art(s) without departing from the spirit and scope of thedisclosure.

As noted above, the power distribution trailer 120 may distribute theelectric power at the power generation voltage level generated by thepower generation system 110 to each of the different VFDs 140(a-n)positioned on the corresponding pump trailer 130(a-n). FIG. 2illustrates a top-elevational view of a single pump configuration 200that includes a single VFD 240, a single shaft electric motor 250 and asingle hydraulic pump 260 that are each mounted on a single pump trailer230. The single pump configuration 200 shares many similar features witheach pump trailer 130(a-n) that includes each corresponding VFD140(a-n), single shaft electric motor 150(a-n), and single hydraulicpump 160(a-n) depicted in the hydraulic fracking operation 100;therefore, only the differences between the single pump configuration200 and the hydraulic fracking operation 100 are to be discussed infurther details.

The power distribution trailer 120 may distribute the electric power atthe voltage level generated by the power generation system 110 to thesingle VFD 240 that is positioned on the single pump trailer 130(a-n).The single VFD 240 may then drive the single shaft electric motor 250and the single hydraulic pump 260 as well as control the operation ofthe single shaft electric motor 250 and the single hydraulic pump 260 asthe single shaft electric motor 250 continuously drives the singlehydraulic pump 260 as the single hydraulic pump 260 continuously pumpsthe fracking media into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the well. Indoing so, the VFD 240 may convert the electric power distributed by thepower distribution trailer 120 at the power generation voltage levelgenerated by the power generation system 110 to a VFD voltage level thatis a voltage level that is adequate to drive the single shaft electricmotor 250. Often times, the power generation voltage level of theelectric power distributed by the power distribution trailer 120 asgenerated by the power generation system 110 may be at a voltage levelthat is significantly higher than a voltage level that is adequate todrive the single shaft electric motor 250. Thus, the single VFD 240 mayconvert the power generation voltage level of the electric power asdistributed by the power distribution trailer 120 to significantly lower(or higher) the voltage level to the VFD voltage level that is needed todrive the single shaft electric motor 250. In an embodiment, the singleVFD 240 may convert the power generation voltage level of the electricpower as distributed by the power distribution trailer 120 to the VFDvoltage level of at least 4160V. In another embodiment, the single VFD240 may convert the power generation voltage level of the electric poweras distributed by the power distribution trailer 120 to the VFD voltagelevel that ranges from 4160V to 6600V. In another embodiment, the singleVFD 240 may convert the power generation level of the electric power asdistributed by the power distribution trailer 120 to the VFD voltagelevel that ranges from 0V to 4160V.

For example, the power generation system 110 generates the electricpower at a power generation voltage level of 13.8 kV. The powerdistribution trailer 120 then distributes the electric power at thepower generation voltage level of 13.8 kV to the single VFD 240.However, the single shaft electric motor 250 operates at a rated voltagelevel of at least 4160V in order to drive the single hydraulic pump 260in which the rated voltage level of at least 4160V for the single shaftelectric motor 250 to operate is significantly less than the powergeneration voltage level of 13.8 kV of the electric power that isdistributed by the power distribution trailer 120 to the single VFD 240.The single VFD 240 may then convert the electric power at the powergeneration voltage level of at least 13.8 kV distributed from the powerdistribution trailer 120 to a VFD rated voltage level of at least 4160Vand drive the single shaft electric motor 250 that is positioned on thesingle pump trailer 230 at the VFD rated voltage level of at least 4160Vto control the operation of the single shaft electric motor 250 and thesingle hydraulic pump 260. The single VFD 240 may convert any voltagelevel of the electric power distributed by the power distributiontrailer 120 to any VFD voltage level that is adequate to drive thesingle shaft electric motor that will be apparent to those skilled inthe relevant art(s) without departing from the spirit and scope of thedisclosure.

The single VFD 240 may also control the operation of the single shaftelectric motor 250 and the single hydraulic pump 260. The single VFD 240may include a sophisticated control system that may control in real-timethe operation of the single shaft electric motor 250 and the singlehydraulic pump 260 in order for the single shaft electric motor 250 andthe single hydraulic pump 260 to adequately operate to continuously pumpthe fracking media into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the well.Although, the single shaft electric motor 250 and the single hydraulicpump 260 may operate continuously to continuously pump the frackingmedia into the well, such continuous operation may not be continuouslyexecuted with the same parameters throughout the continuous operation.The parameters in which the single shaft electric motor 250 and thesingle hydraulic pump 260 may continuously operate may actually varybased on the current state of the fracking operation. The single VFD 240may automatically adjust the parameters in which the single shaftelectric motor 250 and the single hydraulic pump continuously operate toadequately respond to the current state of the fracking operation.

As noted above, the single VFD 240 may convert the electric power at thepower generation voltage level distributed by the power distributiontrailer 120 to the VFD voltage level that is adequate to drive thesingle shaft electric motor 250. The single shaft electric motor 250 maybe a single shaft electric motor in that the single shaft of theelectric motor is coupled to the single hydraulic pump 260 such that thesingle shaft electric motor 250 drives a single hydraulic pump in thesingle hydraulic pump 260. The single shaft electric motor 250 maycontinuously drive the single hydraulic pump 260 at an operatingfrequency to enable the single hydraulic pump 260 to continuously pumpthe fracking media into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the well.The single shaft electric motor 250 may operate at the VFD voltagelevels and at the operating frequencies below or above the rated levelsin order to rotate at a RPM level that is appropriate to continuouslydrive the single hydraulic pump 260 at the maximum horsepower (HP) levelthat the single hydraulic pump 260 is rated to pump. In an embodiment,the single shaft electric motor 250 may operate at a VFD voltage levelof at least 4160V. In an embodiment, the single shaft electric motor 250may operate at a VFD voltage level in a range of 4160V to 6600V. In anembodiment, the single shaft electric motor 250 may operate at a VFDvoltage level in arrange of 0V to 4160V. The single shaft electric motor250 may operate any VFD voltage level that is adequate to continuouslydrive the single hydraulic pump 260 that will be apparent to thoseskilled in the relevant art(s) without departing from the spirit andscope of the disclosure.

For example, the power distribution trailer 120 may distribute theelectric power to the single VFD 240 at the power generation voltagelevel of 13.8 kV. The single VFD 240 may then convert the electric powerat the power generation voltage level of 13.8 kV to the VFD voltagelevel of 4160V to adequately drive the single shaft electric motor 250.The single shaft electric motor 250 may operate at an operatingfrequency of 60 Hz and when the VFD voltage level of 4160V to adequatelydrive the single shaft electric motor at the operating frequency of 60Hz, the single shaft electric motor 250 may then rotate at a RPM levelof at least 750 RPM. The single shaft electric motor 250 may rotate at aRPM level of at least 750 RPM based on the VFD voltage level of at least4160V as provided by the single VFD 240 and to drive the singlehydraulic pump 260 that is positioned on the single pump trailer 230with the single VFD 240 and the single shaft electric motor 250 with therotation at the RPM level of at least 750 RPM.

In an embodiment, the single shaft electric motor 250 may rotate at aRPM level of at least 750 RPM. In an embodiment, the single shaftelectric motor 250 may rotate at a RPM level of 750 RPM to 1400 RPM. Thesingle shaft electric motor 250 may operate at any RPM level tocontinuously drive the single hydraulic pump 260 that will be apparentto those skilled in the relevant art(s) without departing from thespirit and scope of the disclosure. The single shaft electric motor mayoperate at any operating frequency to continuously drive the singlehydraulic pump 260 that will be apparent to those skilled in therelevant art(s) without departing from the spirit and scope of thedisclosure.

The single shaft electric motor 250 may be an induction motor thatrotates at the RPM level needed to obtain required pump speed based onthe input gear box ratio of the single hydraulic pump 260. Based on theoperating frequency of the single shaft motor 250 and the VFD voltagelevel applied to the single shaft electric motor 250, the single shaftelectric motor 250 may then rotate at the required RPM level and producesufficient torque to cause the pump to produce the required flow rate offracking media at the required output pressure level. However, the VFDvoltage level applied to the single shaft electric motor 250 may bedetermined based on the input gear box ratio of the single hydraulicpump 260 as the single shaft electric motor 250 cannot be allowed torotate at the RPM level that exceeds the maximum speed rating of theinput gear box of the single hydraulic pump 260 or the maximum speed ofthe single hydraulic pump 260. The single shaft electric motor 250 maybe an induction motor, a traction motor, a permanent magnet motor and/orany other electric motor that continuously drives the single hydraulicpup 260 that will be apparent to those skilled in the relevant art(s)without departing from the spirit and scope of the disclosure.

As noted above, the single shaft electric motor 250 may be coupled to asingle hydraulic pump in the single hydraulic pump 260 and drive thesingle hydraulic pump 260 such that the single hydraulic pump 260continuously pumps the fracking media into the well to execute thefracking operation to prepare the well for the later extraction of thefluid from the existing well. The single hydraulic pump 260 may operateon a continuous duty cycle such that the single hydraulic pump 260continuously pumps the fracking media into the well. Rather thanoperating on an intermittent duty cycle that causes conventionalhydraulic pumps to temporarily stall in the pumping of the frackingmedia into the well, the single hydraulic pump 260 in operating on acontinuous duty cycle may continuously pump the fracking media into thewell without any intermittent stalling in the pumping. In doing so, theefficiency in the fracking operation to prepare the well for the laterextraction of the fluid from the well may significantly increase as anyintermittent stalling in pumping the fracking media into the well mayresult in setbacks in the fracking operation and may increase the riskof sand plugging the existing well. Thus, the single hydraulic pump 260in operating on the continuous duty cycle may prevent any setbacks inthe fracking operation due to the continuous pumping of the frackingmedia into the well.

The single hydraulic pump 260 may continuously pump the fracking mediainto the well at the HP level that the single hydraulic pump 260 israted. The increase in the HP level that the single hydraulic pump 260may continuously pump the fracking media into the well may result in theincrease in the efficiency in the fracking operation to prepare the wellfor later extraction of the fluid from the well. For example, the singlehydraulic pump 260 may continuously pump the fracking media into thewell at the HP level of at least 5000HP as driven by the single shaftmotor 250 at the RPM level of at least 750 RPM. The single hydraulicpump 260 operates on a continuous duty cycle to continuously pump thefracking media at the HP level of at least 5000HP. In an embodiment, thesingle hydraulic pump 260 may operate at continuous duty with a HP levelof 5000HP and may be a Weir QEM5000 Pump. However, the single hydraulicpump 260 may any type of hydraulic pump that operates on a continuousduty cycle and at any HP level that adequately continuously pumps thepumping fracking media into the well to execute the fracking operationto prepare the well for the later extraction of the fluid from the wellthat will be apparent to those skilled in the relevant art(s) withoutdeparting from the spirit and scope of the disclosure.

The single pump trailer 230 discussed in detail above may then beincorporated into the hydraulic fracking operation 100 depicted inFIG. 1. Each of the several pumps trailers 130(a-n), where n is aninteger equal to or greater than one, may be in incorporated into thehydraulic fracking operation 100 to increase the overall HP level thatis applied to the fracking equipment positioned on the fracking trailer170 by each of the single hydraulic pumps 160(a-n) positioned on each ofthe pump trailers 130(a-n). In doing so, the overall HP level that isapplied to the fracking equipment positioned on the fracking trailer 170to continuously pump the fracking media into the well may besignificantly increased as the HP level that is applied to the frackingequipment is scaled with each single hydraulic pump 160(a-n) that isadded to the hydraulic fracking operation 100.

The positioning of each single VFD 140(a-n), single shaft electric motor150(a-n), and each single hydraulic pump 160(a-n) positioned on eachcorresponding pump trailer 130(a-n) enables the power distributiontrailer 120 to distribute the electric power at the power generationvoltage level to each single VFD 140(a-n) from a single powerdistribution source rather than having a corresponding single powerdistribution source for each single VFD 140(a-n), single shaft electricmotor 150(a-n), and each single hydraulic pump 160(a-n). In doing so,the electric power at the power generation voltage level may bedistributed to each single VFD 140(a-n), where n is in an integer equalto or greater than one and corresponds to the number of pump trailers130(a-n), then each single VFD 140(a-n) may individually convert thepower generation voltage level to the appropriate VFD voltage for thesingle shaft electric motor 150(a-n) and the single hydraulic pump160(a-n) that is positioned on the corresponding pump trailer 130(a-n)with the single VFD 140(a-n). The single VFD 140(a-n) may then alsocontrol the corresponding single shaft electric motor 150(a-n) and thesingle hydraulic pump 160(a-n) that is positioned on the correspondingpump trailer 130(a-n) with the single VFD 140(a-n).

In isolating the single VFD 140(a-n) to convert the electric power atthe power generation voltage level to the appropriate VFD voltage levelfor the single shaft electric motor 150(a-n) and the single hydraulicpump 160(a-n) positioned on the corresponding single pump trailer130(a-n) as the single VFD 140(a-n), the capabilities of the single pumptrailer 130(a-n) may then be easily scaled by replicating the singlepump trailer 130(a-n) into several different pump trailers 130(a-n). Inscaling the single pump trailer 130(a-n) into several different pumptrailers 130(a-n), the parameters for the single VFD 140(a-n), thesingle shaft electric motor 150(a-n), and the single hydraulic pump160(a-n) may be replicated to generate the several different pumptrailers 130(a-n) and in doing so scaling the hydraulic frackingoperation 100.

In doing so, each single VFD 140(a-n) may convert the electric power atthe power generation voltage level as distributed by the powerdistribution trailer 120 to the VFD voltage level to drive each singleshaft electric motor 150(a-n), where n is an integer equal to or greaterthan one and corresponds to the quantity of single VFDs 140(a-n) andpump trailers 130(a-n), such that each single shaft electric motor150(a-n) rotates at the RPM level sufficient to continuously drive thesingle hydraulic pump 160(a-n) at the HP level of the single hydraulicpump 160(a-n). Rather than simply having a single hydraulic pump 260 asdepicted in FIG. 2 and discussed in detail above to continuously pump atthe HP level of the single hydraulic pump 260, several differenthydraulic pumps 160(a-n), where n is an integer equal to or greater thanone and corresponds to the to the quantity of single VFDs 140(a-n),single shaft electric motors 150(a-n) and pump trailers 130(a-n), aspositioned on different pump trailers 160 may be scaled together toscale the overall HP level that is provided to the fracking equipment aspositioned on the fracking trailer 170. In doing so, the overall HPlevel that is provided to the fracking equipment to continuously pumpthe fracking media into the well to execute the fracking operation toprepare the well for the later extraction of the fluid from the well maybe easily scaled by incorporating each of the individual pump trailers130(a-n) each with single hydraulic pumps 160(a-n) operating at the HPlevels to scale the HP levels of the single hydraulic pumps 160(a-n) togenerate the overall HP level for the hydraulic fracking operation 100.

For example, each of the single hydraulic pumps 160(a-n) positioned oneach corresponding pump trailer 130(a-n) may be operating on acontinuous duty cycle at a HP level of at least 5000HP. A total of eightpump trailers 130(a-n) each with a single hydraulic pump 160(a-n)positioned on the corresponding pump trailer 130(a-n) results in a totalof eight hydraulic pumps 160(a-n) operating on a continuous duty cycleat a HP level of at least 5000HP. In doing so, each of the eighthydraulic pumps 160(a-n) continuously pump the fracking media into thewell at a HP level of at least 40,000HP and do so continuously with eachof the eight hydraulic pumps 160(a-n) operating on a continuous dutycycle. Thus, the fracking media may be continuously pumped into the wellat a HP level of at least 40,000HP to execute the fracking operation toprepare the well for the later extraction of the fluid from the well.The hydraulic pumps 160(a-n) positioned on each corresponding pumptrailer 130(a-n) may operate on a continuous duty at any HP level andthe and the quantity of pump trailers may be scaled to any quantityobtain an overall HP level for the hydraulic fracking operation 100 thatwill be apparent to those skilled in the relevant art(s) withoutdeparting from the spirit and scope of the disclosure.

Further, conventional hydraulic fracking operations that incorporatediesel engines require a diesel engine to drive each conventionalhydraulic pump rather than being able to consolidate the powergeneration to a power generation system 110 that consolidates thequantity and size of the gas turbine engines to generate the electricpower. Such an increase in diesel engines significantly increases thecost of the fracking operation in that significantly more trailersand/or significantly over size/weight trailers are required to transportthe diesel engines resulting in significantly more and/or specializedsemi-trucks and/or trailers required to transport the diesel engineswhich requires significantly more CDL drivers. As the overall assetcount increases at the fracking site, the overall cost increases due tothe increased amount of manpower required, the costs and delays relatedto permitted loads, as well as an increase in the amount of rigging thatis required to rig each of the diesel engines to the conventionalhydraulic pumps and so on. Rather, the electric driven hydraulicfracking operation 100 decreases the asset count by consolidating thepower generation to the gas turbine engines of decreased size andquantity that are consolidated into the power generation system 110. Thepower distribution trailer 120 then further decreases the cost byconsolidating the medium voltage cabling that is required to power eachof the assets thereby decreasing the amount of rigging required.

Further, conventional hydraulic fracking operations that incorporatediesel engines suffer significant parasitic losses throughout thedifferent components included in the fracking operation. Diesel enginesthat generate at a power level equal to the rated power level of theconventional fracking pumps may not result in delivering the full ratedpower to the pump due to parasitic losses throughout the conventionaldiesel fracking trailer configuraiton. For example, the diesel enginesmay suffer parasitic losses when driving the hydraulic coolers and thelube pumps that are associated with the conventional hydraulic pump inaddition to the parasitic losses suffered from driving the conventionalhydraulic pump itself. In such an example, the diesel engine may bedriving the conventional hydraulic pump that is rated at 2500HP at theHP level of 2500HP but due to parasitic losses, the diesel engine isactually only driving the conventional hydraulic pump at 85% of the HPlevel of 2500HP due to the parasitic losses. However, the electricdriven hydraulic fracking operation 100 may have the single hydraulicpump 160(a-n) that is rated at the HP level of 5000HP, however, theparasitic loads are controlled by equipment running in parallel with thesingle hydraulic pump 160(a-n), thus the single VFD 140(a-n) associatedwith each corresponding single hydraulic pump 160(a-n) provides all ofits output electric power to the single hydraulic pump 160(a-n), thesingle hydraulic pump 160(a-n) actually continuously pumps the frackingmedia into the well at 5000HP. Thus, the asset count required for theelectric driven hydraulic fracking operation 100 is significantlyreduced as compared to the hydraulic fracking operations thatincorporate diesel engines due to the lack of parasitic losses for theelectric driven hydraulic fracking operation 100.

Further, the conventional hydraulic fracking operations that incorporatediesel engines generate significantly more noise than the electricdriven hydraulic fracking operation 100. The numerous diesel enginesrequired in the conventional hydraulic fracking operations generateincreased noise levels in that the diesel engines generate noise levelsat 110 Dba. However, the gas turbine engines incorporated into the powergeneration system 110 of the electric driven hydraulic frackingoperation 100 generate noise levels that are less than 85 Dba. Oftentimes, the fracking site has noise regulations associated with thefracking site in that the noise levels of the fracking operation cannotexceed 85 Dba. In such situations, an increased cost is associated withthe conventional hydraulic fracking operations that incorporate dieselengines in attempts to lower the noise levels generated by the dieselengines to below 85 Dba or having to build sound walls to redirect thenoise in order to achieve noise levels below 85 Dba. The electric drivenfracking operation 100 does not have the increased cost as the noiselevels of the oilfield gas turbine engines include silencers and stacks,thus they already fall below 85 Dba.

Further, the increase in the quantity of conventional hydraulic pumpsfurther increases the asset count which increases the cost as well asthe cost of operation of the increase in quantity of conventionalhydraulic pumps. Rather than having eight single hydraulic pumps160(a-n) rated at the HP level of 5000HP to obtain a total HP level of40000HP for the fracking site, the conventional hydraulic frackingsystems require sixteen conventional hydraulic pumps rated at the HPlevel of 2500HP to obtain the total HP level of 40000HP. In doing so, asignificant cost is associated with the increased quantity ofconventional hydraulic pumps. Further, conventional hydraulic pumps thatfail to incorporate a single VFD 140(a-n), a single shaft electric motor150(a-n), and a single hydraulic pump 160(a-n) onto a single pumptrailer 130(a-n) further increase the cost by increasing additionaltrailers and rigging required to set up the numerous differentcomponents at the fracking site. Rather, the electric driven hydraulicfracking operation 100 incorporates the power distribution trailer 120to consolidate the power generated by the power generation system 110and then limit the distribution and the cabling required to distributethe electric power to each of the single pump trailers 130(a-n).

In addition to the fracking equipment positioned on the fracking trailer170 that is electrically driven by the electric power generated by thepower generation system 110 and each of the VFDs 140(a-n), single shaftelectric motors 150(a-n), and the single hydraulic pumps 160(a-n) thatare also electrically driven by the electric power generated by thepower generation system 110, a plurality of auxiliary systems 190 may bepositioned at the fracking site may also be electrically driven by theelectric power generated by power generation system 110. The auxiliarysystems 190 may assist each of the single hydraulic pumps 160(a-n) aswell as the fracking equipment positioned on the fracking trailer 170 aseach of the hydraulic pumps 160(a-n) operate to execute the frackingoperation to prepare the well for the later extraction of the fluid fromthe well. In doing so, the auxiliary systems 190 may be systems inaddition to the fracking equipment positioned on the fracking trailer170 and the single hydraulic pumps 160(a-n) that are required to preparethe well for the later execution of the fluid from the well.

For example, the auxiliary systems 190, such as a hydration system thatprovides adequate hydration to fracking media as the single hydraulicpumps 160(a-n) continuously pump the fracking media into the well. Thus,auxiliary systems 190 may include but are not limited to hydrationsystems, chemical additive systems, blending systems, sand storage andtransporting systems, mixing systems and/or any other type of systemthat is required at the fracking site that is addition to the frackingequipment positioned on the fracking trailer 170 and the singlehydraulic pumps 160(a-n) that may be electrically driven by the electricpower generated by the power generation system 110 that will be apparentto those skilled in the relevant art(s) without departing from thespirit and scope of the disclosure.

The electric power generated by the power generation system 110 may thusbe distributed by the power distribution trailer 120 such that theelectric power generated by the power generation system 110 may also beincorporated to power the auxiliary systems 190. In doing so, theelectric power generated by the power generation system 110 may beincorporated to not only drive the pump trailers 130(a-n) via the singleVFDs 140(a-n) positioned on each pump trailer 130(a-n) but to also powerthe auxiliary systems 190. Thus, the hydraulic fracking operation 100may be completely electric driven in that each of the required systemspositioned on the fracking site may be powered by the electric powergenerated by the electric power that is consolidated to the powergeneration system 110.

As noted above, each of the single VFDs 140(a-n) may include asophisticated control system that may control in real-time the operationof the single shaft electric motors 150(a-n) and the single hydraulicpumps 160(a-n) in order for the single shaft electric motors 150(a-n)and the single hydraulic pumps 160(a-n) to optimally operate tocontinuously pump the fracking media into the well to execute thefracking operation to prepare the well for the later extraction of thefluid from the well. However, the fracking control center 180 that maybe positioned at the fracking site and/or remote from the fracking sitemay also control the single VFDs 140(a-n) and in doing so control thereal-time operation of the single shaft electric motors 150(a-n) and thesingle hydraulic pumps 160(a-n) in order for the single shaft electricmotors 150(a-n) and the single hydraulic pumps 160(a-n) to optimallyoperate to continuously pump the fracking media into the well to executethe fracking operation to extract the fluid from the well. In doing so,the fracking control center 180 may intervene to control the single VFDs140(a-n) when necessary. The fracking control center 180 may alsocontrol the fracking equipment positioned on the fracking trailer 170 aswell as the auxiliary systems 190 in order to ensure that the frackingoperation is optimally executed to prepare the well for the laterextraction of the fluid from the well.

Communication between the fracking control center 180 and the singleVFDs 140(a-n), the fracking equipment positioned on the fracking trailer170, and/or the auxiliary systems 190 may occur via wireless and/orwired connection communication. Wireless communication may occur via oneor more networks 105 such as the internet or Wi-Fi wireless accesspoints (WAP. In some embodiments, the network 105 may include one ormore wide area networks (WAN) or local area networks (LAN). The networkmay utilize one or more network technologies such as Ethernet, FastEthernet, Gigabit Ethernet, virtual private network (VPN), remote VPNaccess, a variant of IEEE 802.11 standard such as Wi-Fi, and the like.Communication over the network 105 takes place using one or more networkcommunication protocols including reliable streaming protocols such astransmission control protocol (TCP), Ethernet, Modbus, CanBus, EtherCAT,ProfiNET, and/or any other type of network communication protocol thatwill be apparent from those skilled in the relevant art(s) withoutdeparting from the spirit and scope of the present disclosure. Wiredconnection communication may occur but is not limited to a fiber opticconnection, a coaxial cable connection, a copper cable connection,and/or any other type of direct wired connection that will be apparentfrom those skilled in the relevant art(s) without departing from thespirit and scope of the present disclosure. These examples areillustrative and not intended to limit the present disclosure.

Electric Power Distribution and Control

FIG. 3 illustrates a block diagram of an electric driven hydraulicfracking system that provides an electric driven system to execute afracking operation in that the electric power is consolidated in a powergeneration system and then distributed such that each component in theelectric driven hydraulic fracking system is electrically powered. Anelectric driven hydraulic fracking system 300 includes a powergeneration system 310, a power distribution trailer 320, a plurality ofpump trailers 330(a-n), a plurality of single VFDs 340(a-n), aswitchgear configuration 305, a plurality of trailer auxiliary systems315(a-n), a plurality of switchgears 325(a-n), a switchgear transformerconfiguration 335, and fracking equipment 370. The electric power isconsolidated in the power generation system 310 and then distributed atthe appropriate voltage levels by the power distribution trailer 320 todecrease the medium voltage cabling required to distribute the electricpower. The single VFDs 340(a-n) and the trailer auxiliary systems315(a-n) positioned on the pump trailers 330(a-n) as well as thefracking control center 380 and auxiliary systems 390 are electricallypowered by the electric power that is consolidated and generated by thepower generation system 310. The electric driven hydraulic frackingsystem 300 shares many similar features with the hydraulic frackingoperation 100 and the single pump configuration 200; therefore, only thedifferences between the electric driven hydraulic fracking system 300and the hydraulic fracking operation 100 and single pump configuration200 are to be discussed in further detail.

As noted above, the power generation system 310 may consolidate theelectric power 350 that is generated for the electric driven hydraulicfracking system 300 such that the quantity and size of the power sourcesincluded in the power generation system 310 is decreased. As discussedabove, the power generating system 310 may include numerous powersources as well as different power sources and any combination thereof.For example, the power generating system 310 may include power sourcesthat include a quantity of gas turbine engines. In another example, thepower generation system 310 may include a power source that includes anelectric power plant that independently generates electric power for anelectric utility grid. In another example, the power generation system310 may include a combination of gas turbine engines and an electricpower plant. The power generation system 310 may generate the electricpower 350 at a power level and a voltage level.

The power generation system 310 may generate electric power at a powergeneration voltage level in which the power generation voltage level isthe voltage level that the power generation system is capable ofgenerating the electric power 350. For example, the power generationsystem 310 when the power sources of the power generation system 310include a quantity of gas turbine engines may generate the electricpower 350 at the voltage level of 13.8 kV which is a typical voltagelevel for electric power 350 generated by gas turbine engines. Inanother example, the power generation system 310 when the power sourcesof the power generation system include an electric power plan maygenerate the electric power 350 at the voltage level of 12.47 kV whichis a typical voltage level for electric power 350 generated by anelectric power plant. The power generation system may generate theelectric power 350 at any voltage level that is provided by the powersources included in the power generation system 310 that will beapparent to those skilled in the relevant art(s) without departing fromthe spirit and scope of the disclosure. The power generation system 310may then provide the electric power 350 at the voltage level 13.8 kV tothe power distribution trailer 320 via a medium voltage cable.

In continuing for purposes of discussion, the power distribution trailer320 may then distribute the electric power 350 at the power generationvoltage level to a plurality of single VFDs 340(a-n), where n is aninteger equal to or greater than two, with each single VFD 340(a-n)positioned on a corresponding single trailer 330(a-n) from a pluralityof single trailers, where n is an integer equal to or greater than two.The power distribution trailer 320 may include a switchgearconfiguration 305 that includes a plurality of switchgears 325(a-n),where n is an integer equal to or greater than two, to distribute theelectric power 350 generated by the at least one power source includedin the power distribution trailer 310 at the power generation voltagelevel 360 to each corresponding single VFD 340(a-n) positioned on eachcorresponding trailer 330(a-n).

Since the electric power 350 is consolidated to the power generationsystem 310, the switch gear configuration 305 of the power distributiontrailer 320 may distribute the electric power 350 at the powergeneration voltage level as generated by the power generation system 310to each of the single VFDs 340(a-n) as electric power 360 at the powergeneration voltage level such that the each of the single VFDs 340(a-n)may then drive the single shaft electric motors and the single hydraulicpumps as discussed in detail below. For example, the switch gearconfiguration 305 of the power distribution trailer 320 may distributethe electric power 350 at the power generation voltage level of 13.8 kVto each of the single VFDs 340(a-n) as electric power 360 at the powergeneration voltage level of 13.8 kV when the power distribution system310 has power sources that include gas turbine engines. In anotherexample, the switch gear configuration 305 of the power distributiontrailer 320 may distribute the electric power 350 at the powergeneration level of 12.47 kV to each of the single VFDs 340(a-n) aselectric power 360 at the power generation level of 12.47 kV when thepower distribution 310 has power sources that include an electric powerplant.

In order for the electric power to be consolidated to the powergeneration system 310 as well as to provide an electric driven system inwhich each of the components of the electric driven hydraulic frackingsystem 300 is driven by the electric power generated by the powergeneration system 310, the power distribution trailer 320 provides theflexibility to distribute the electric power 350 generated by the powergeneration system 310 at different voltage levels. In adjusting thevoltage levels that the electric power 350 generated by the powergeneration system 310 is distributed, the power distribution trailer 320may then distribute the appropriate voltage levels to several differentcomponents included in the electric driven hydraulic fracking system 300to accommodate the electric power requirements of the several differentcomponents included in the electric driven hydraulic fracking system300. For example, the power distribution trailer 320 may distribute theelectric power 360 generated by the power generation system 310 at thevoltage level of 13.8 kV as generated by the power generation system 310via the switch gears 325(a-n) to each of the single VFDs 340(a-n) forthe each of the single VFDs 340(a-n) to drive the single shaft electricmotors and the single hydraulic pumps. In another example, the powerdistribution trailer 320 may distribute the electric power 360 generatedby the power generation system 310 at the voltage level of 12.47 kV asgenerated by the power generation system 310 via the switch gears325(a-n) to each of the single VFDs 340(a-n) for each of the single VFDs340(a-n) to drive the single shaft electric motors and the singlehydraulic pumps.

However, the electric power distribution trailer 320 may also distributethe electric power 350 generated by the power generation system 310 at adecreased voltage level from the voltage level of the electric power 350originally generated by the power generation system 310. Severaldifferent components of the electric driven hydraulic fracking system300 may have power requirements that require electric power at asignificantly lower voltage level than the electric power 350 originallygenerated by the power generation system 310. In doing so, the powerdistribution trailer 320 may include a switchgear transformerconfiguration 335 that may step-down the voltage level of the electricpower 350 as originally generated by the power distribution trailer 310to a lower voltage level that satisfies the power requirements of thosecomponents that may not be able to handle the increased voltage level ofthe electric power 350 originally generated by the power distributiontrailer 310. In doing so, the electric power distribution trailer 320may provide the necessary flexibility to continue to consolidate theelectric power 350 to the power generation system 310 while stillenabling each of the several components to be powered by the electricpower generated by the power generation system 310.

For example, the switchgear transformer configuration 335 may convertthe electric power 350 generated by the at least one power source of thepower generation system 310 at the power generation voltage level to atan auxiliary voltage level that is less than the power generationvoltage level. The switchgear transformer configuration 335 may thendistribute the electric power 355 at the auxiliary voltage level to eachsingle VFD 340(a-n) on each corresponding single trailer 330(a-n) toenable each single VFD 340(a-n) from the plurality of single VFDs340(a-n) to communicate with the fracking control center 380. Theswitchgear transformer configuration 335 may also distribute theelectric power 355 at the auxiliary voltage level to a plurality ofauxiliary systems 390. The plurality of auxiliary systems 390 assistseach single hydraulic pump as each hydraulic pump from the plurality ofsingle hydraulic pumps operate to prepare the well for the laterextraction of the fluid from the well.

In such an example, the switchgear transformer configuration 335 mayconvert the electric power 350 generated by the power generation system310 with power sources include gas turbine engines at the powergeneration voltage level of 13.8 kV to an auxiliary voltage level of480V that is less than the power generation voltage level of 13.8 kV.The switchgear transformer configuration 335 may then distribute theelectric power 355 at the auxiliary voltage level of 480V to each singleVFD 340(a-n) on each corresponding single trailer 330(a-n) to enableeach single VFD 340(a-n) from the plurality of single VFDs 340(a-n) tocommunicate with the fracking control center 380. The switchgeartransformer configuration 335 may also distribute the electric power 355at the auxiliary voltage level of 480V to a plurality of auxiliarysystems 390. In another example, the switchgear transformerconfiguration 335 may convert the electric power 350 generated by thepower generation system 310 with power sources that include an electricpower plant at the power generation voltage level of 12.47 kV to anauxiliary voltage level of 480V that is less than the power generationvoltage level of 12.47 kV. In another example, the switchgeartransformer configuration 33 may convert the electric power 350 at thepower generation voltage level generated by the power generation system310 to the auxiliary voltage level of 480V, 120V, 24V and/or any otherauxiliary voltage level that is less than the power generation voltagelevel. The switchgear transformer configuration 335 may convert theelectric power 350 at the power generation voltage level generated bythe power generation system 310 to any auxiliary voltage level that isless than the power generation voltage level to assist each single VFD340(a-n) in executing operations that do not require the electric power360 at the power generation voltage level that will be apparent to thoseskilled in the relevant art(s) without departing from the spirit andscope of the disclosure.

Unlike each of the single VFDs 340(a-n) that may convert the electricpower 360 at the power generation voltage level to drive the singleshaft electric motors and the single hydraulic pumps, the frackingcontrol center 380, the auxiliary systems 390, the trailer auxiliarysystems 315(a-n) as well as the operation of features of the single VFDS340(a-n) that are unrelated to the driving of the single shaft electricmotors and the single hydraulic pumps require the electric power to bestepped down to the electric power 355 at the auxiliary voltage level.The switchgear transformer configuration 335 may provide the necessaryflexibility to step-down the electric power 360 at the power generationvoltage level to the generate the electric power 355 at the auxiliaryvoltage level such that the remaining components of the electric drivenhydraulic fracking system 300 may also be electrically driven by theelectric power consolidated to the power generation system 310.

In stepping down the electric power 350 generated by the powergeneration system 310 at the power generation voltage level, theswitchgear transformer configuration 335 may provide the electric power355 at the auxiliary voltage level to the auxiliary systems 390. Indoing so, the auxiliary systems 390 may be electrically driven by theelectric power 355 at the auxiliary voltage level such that the electricpower consolidated by the power generation system 310 may drive theauxiliary systems 390. The auxiliary systems 390 may include but are notlimited hydration systems, chemical additive systems, fracturingsystems, blending systems, mixing systems and so on such that each ofthe auxiliary systems 390 required to execute the fracking operation maybe electrically driven by the electric power consolidated by the powergeneration system 310. Further, the power distribution trailer 320 mayalso route a communication link 365 to each of the auxiliary systems 390such that the fracking control center 380 may intervene and control eachof the auxiliary systems 390 via the communication link 365 ifnecessary.

The switchgear transformer configuration 335 may also provide theelectric power 355 at the auxiliary voltage level to the frackingcontrol center 380. In providing the auxiliary voltage level to thefracking control center 380, the fracking control center 380 mayremotely control the auxiliary systems 390, the single VFDs 340(a-n), aswell as the trailer auxiliary systems 315(a-n) as requested by thefracking control center 380. The power distribution trailer 320 mayroute the communication link 365 to the auxiliary systems 390, thesingle VFDs 340(a-n), and the trailer auxiliary systems 315(a-n) suchthat the fracking control center 380 may communicate with each of theauxiliary systems 390, the single VFDs 340(a-n), and the trailerauxiliary systems 315(a-n) and thereby control via the communicationlink 365. As discussed above, the communication link 365 may be awireline and/or wireless communication link.

The switchgear transformer configuration 335 may also provide theelectric power 355 at the auxiliary voltage level to each of the singleVFDs 340(a-n). As discussed above and below, the single VFDs 340(a-n)convert the electric power 360 generated by the power generation system310 at the power generation voltage level to drive the single shaftelectric motors and the single hydraulic pumps. However, the single VFD340(a-n) may also operate with different functionality without having todrive the single shaft electric motors and the single hydraulic pumps.For example, the auxiliary systems 315(a-n) positioned on the pumptrailers 330(a-n) and/or included in the single VFDs 340(a-n) mayoperate as controlled by a corresponding VFD controller 345(a-n) that ispositioned on the corresponding single trailer 330(a-n) and associatedwith the corresponding single VFD 340(a-n).

In doing so, the single VFD controllers 345(a-n) may operate theauxiliary systems 315(a-n) when the single VFD 340(a-n) is simplyprovided the electric power 355 at the auxiliary voltage level ratherthan having to operate with the electric power 360 at the powergeneration voltage level. In doing so, the fracking control center 380may also communicate with the VFD controllers 345(a-n) and the singleVFDs 340(a-n) as well as the trailer auxiliary systems 315(a-n) via thecommunication link 365 when the stepped-down electric power 355 at theauxiliary voltage level is provided to each of the single VFDs 340(a-n).In addition to operating auxiliary systems 315(a-n) when thecorresponding single VFD 340(a-n) is provided the electric power 355 atthe auxiliary voltage level, the VFD controller 345(a-n) may alsooperate the trailer auxiliary systems 315(a-n) as well as control thecorresponding single shaft electric motor 150(a-n) that then drives eachof the corresponding hydraulic pumps 160(a-n) to continuously pump thefracking media into the well to execute the fracking operation toextract the fluid from the well when the electric power 360 at the powergeneration voltage level is provided to the single VFDs 340(a-n).

For example, the single VFDs 340(a-n) may operate at a reduced capacitywhen the switchgear transformer configuration 335 provides the electricpower 355 at the auxiliary voltage level. In doing so, the single VFDs340(a-n) may operate in a maintenance mode in which the electric power355 at the auxiliary voltage level is sufficient for the single VFDs340(a-n) to spin the single shaft electric motors but not sufficient todrive the single shaft electric motors at the RPM levels that the singleshaft electric motors are rated. In operating the single VFDs 340(a-n)in the maintenance mode with the electric power 355 at the auxiliaryvoltage level, the hydraulic pumps as well as the fracking equipment 370may be examined and maintenance may be performed on the hydraulic pumpsand the fracking equipment 370 to ensure the hydraulic pumps 160(a-n)and the fracking equipment 370 are operating adequately. The VFDcontrollers 345(a-n) of the single VFDs 340(a-n) may execute thefunctionality of the single VFDs 340(a-n) when operating in themaintenance mode. The fracking control center 380 may also remotelycontrol the single VFDs 340(a-n) via the communication link 365 toexecute the functionality of the single VFDs 340(a-n) when operating inthe maintenance mode.

In another example, the trailer auxiliary systems 315(a-n) may beoperated when the single VFDs 340(a-n) are operating at the reducedcapacity when the switchgear transformer configuration 335 provides theelectric power 355 at the auxiliary voltage level. The trailer auxiliarysystems 315(a-n) may be auxiliary systems positioned on the pumptrailers 330(a-n) and/or included in the single VFDs 340(a-n) such thatauxiliary operations may be performed on the single VFDs 340(a-n), thesingle shaft electric motors, and/or the single hydraulic pumps toassist in the maintenance and/or operation of the single VFDs 340(a-n)the single shaft electric motors and/or single hydraulic pumps when theelectric power 355 at the auxiliary voltage level is provided to thesingle VFDs 340(a-n). For example, the trailer auxiliary systems315(a-n) may include but are not limited to motor blower systems, thelube oil controls, oil heaters, VFD fans, and/or any other type ofauxiliary system that is positioned on the pump trailers 330(a-n) and/orincluded in the single VFDs 340(a-n) to assist in the maintenance and/oroperation of the single VFDs 340(a-n), single shaft electric motors,and/or single hydraulic pumps that will be apparent to those skilled inthe relevant art(s) without departing from the spirit and scope of thedisclosure.

As discussed above, FIG. 3 summarizes the functionality of the ofdistribution of the electric power 350 as generated by the powergeneration system 310 and then distributed by the power distributiontrailer 320 with regard to how the electric power 350 is provided toeach of the single VFDs 340(a-n) positioned on each of the correspondingpump trailers 330(a-n). FIG. 4 illustrates a block diagram of anelectric driven hydraulic fracking system 400 that further describes theincorporation of the power distribution trailer 320 into the electricdriven hydraulic fracking system 400. The power distribution trailer 320includes a power distribution trailer controller 430, an auxiliarysystem transformer 410, an additional system transformer 420 thatprovides electric power 350 to an additional system 440, and theincorporation of a black start generator 405.

The switchgear transformer configuration 335 as discussed generally inFIG. 3 is discussed in more detail below with regard to FIG. 4 in thatthe electric power 350 distributed by the power distribution trailer 320may be further customized to provide electric power 350 at severaldifferent voltage levels to different systems included in the electricdriven hydraulic fracking system 400. The electric driven hydraulicfracking system 400 shares many similar features with the hydraulicfracking operation 100, the single pump configuration 200, and theelectric driven hydraulic fracking system 300; therefore, only thedifferences between the electric driven hydraulic fracking system 400and the hydraulic fracking operation 110, the single pump configuration200, and the electric driven hydraulic fracking system 300 are to bediscussed in further detail.

As noted above, the trailer auxiliary systems 315(a-n) as well as theoperation of features of the single VFDS 340(a-n) that are unrelated tothe driving of the single shaft electric motors and the single hydraulicpumps require the electric power 350 to be stepped down to the electricpower 355 at the auxiliary voltage level. The switchgear transformerconfiguration 335 may provide the necessary flexibility to step-down theelectric power 360 at the power generation voltage level to generate theelectric power 355 at the auxiliary voltage level such that theremaining components of the electric driven hydraulic fracking system300 may also be electrically driven by the electric power 350consolidated to the power generation system 310. Specifically, theswitchgear transformer configuration 335 includes the auxiliarytransformer 410 and the additional system transformer 420 as well as anyother transformer necessary to customize the electric power 350distributed by the power distribution trailer 320 to differentiate thepower generation voltage level 360 of the electric power 350 to theappropriate voltage levels, such as the voltage level of 480V, requiredto power other systems that do not have the capability to step-down thepower generation voltage level 360 to lower voltages and/or simplyrequire significantly lower voltages to operate.

For example, the auxiliary system transformer 410 may step-down theelectric power 350 generated at the voltage level of 13.8 kV anddistribute the electric power 355 at the auxiliary voltage level of 480Vto each single VFD 340(a-n) on each corresponding single trailer330(a-n) to enable each single VFD 340(a-n) from the plurality of singleVFDs 340(a-n) to communicate with the fracking control center 380. Theauxiliary system transformer 410 may also step-down the electric power350 to the electric power 355 at the auxiliary voltage level of 480V toeach single VFD 340(a-n) such that each single VFD 340(a-n) may operateat a reduced capacity to enable each VFD controller 345(a-n) operate thetrailer auxiliary systems 315(a-n) without having to actually operate ina full capacity via the electric power 350 generated at the voltagelevel of 13.8 kV. In doing so, the auxiliary system transformer 410 mayenable the VFD controller 345(a-n) to operate the trailer auxiliarysystems 315(a-n) such as the motor blower systems, the lube oilcontrols, oil heaters, VFD fans, and/or any other type of auxiliarysystem that is positioned on the pump trailers 330(a-n) and/or includedin the single VFDs 340(a-n) without having to have the electric power360 at the voltage level of 13.8 kV provided to the single VFDs340(a-n).

The auxiliary system transformer 410 may also step-down the electricpower 350 generated at the power generation voltage level and distributethe electric power 355 at the auxiliary voltage level to each single VFD340(a-n) on each corresponding single trailer 330(a-n) to enable atransformer included with each single VFD 340(a-n) to be pre-magnetizedbefore opening each single VFD 340(a-n) to the electric power 360 at thepower generation voltage level. Each single VFD 340(a-n) when activatedby the electric power 360 at the power generation voltage level maygenerate a significant in-rush of current due to the significant amountof current that each single VFD 340(a-n) may generate once activated bythe electric power 360 at the power generation voltage level. Thesignificant in-rush of current generated by each single VFD 340(a-n)once activated by the electric power 360 at the power generation voltagelevel may then propagate back to the power generation system 310 andhave a negative impact on the power generation system 310.

For example, the power generation system 310 is an electric power plantthat generates the electric power 360 at the power generation voltagelevel of 12.47 kV and provides such electric power 350 to the powerdistribution trailer 320 to be distributed to each single VFD 340(a-n).The electric power plant 310 often times independently generateselectric power for an electric utility grid. A significant in-rush ofcurrent generated from each single VFD 340(a-n) after each single VFD340(a-n) is activated by the electric power 360 at the power generationvoltage level of 12.47 kV that is then propagated back to the electricpower plant 310 may negatively impact the electric utility grid that theelectric power plant 310 independently generates electric power for.Thus, the operators of the electric power plant 310 require that thein-rush of current that is propagated back to the electric power plant310 generated by each single VFD 340(a-n) be significantly mitigated.

In order to significantly mitigate the in-rush of current that ispropagated back to the power generation system 310 after each single VFD340(a-n) is activated by the electric power 360 at the power generationvoltage level, each single VFD 340(a-n) may include a transformer (notshown). The auxiliary system transformer 410 may provide the electricpower 355 at the auxiliary voltage level to each transformer includedwith each single VFD 340(a-n). Each transformer may isolate eachcorresponding single VFD 340(a-n) from the electric power 360 at thepower generation voltage level while each transformer is pre-magnetizedwith the electric power 355 at the auxiliary voltage level as providedby the auxiliary system transformer 410. Each transformer may thenactivate each corresponding single VFD 340(a-n) with the electric power355 at the auxiliary voltage level by pre-charging the capacitorsassociated with each single VFD 340(a-n) with the electric power 355 atthe auxiliary voltage level.

In doing so, each single VFD 340(a-n) may essentially be exposed to theelectric power 355 at the auxiliary voltage level and pre-charge to avoltage threshold of the electric power 355 at the power generationvoltage level. For example, the each single VFD 340(a-n) may pre-chargewith the electric power 355 at the auxiliary voltage level to thevoltage threshold of 20% to 25% of the electric power 360 at the powergeneration voltage level. The voltage threshold may be any percentage ofthe electric power 360 at the power generation voltage level that eachsingle VFD 340(a-n) is to pre-charge to prevent an in-rush of currentthat may negatively impact the power generation system 310 that will beapparent to those skilled in the relevant art(s) without departing fromthe spirit and scope of the disclosure.

After each single VFD 340(a-n) has pre-charged to the voltage thresholdbased on the electric power 355 at the auxiliary voltage level asprovided by the auxiliary system transformer 410, each correspondingtransformer may then transition to enable each single VFD 340(a-n) tothen be exposed to the electric power 360 at the power generationvoltage level. In doing so, each single VFD 340(a-n) may then be poweredby the electric power 360 at the power generation voltage level andthereby decrease to the VFD voltage level of at least 4160V to drive thesingle shaft electric motor 150(a-n) and the single hydraulic pump160(a-n). However, the in-rush of current that may propagate back to thepower generation system 310 may be significantly reduced due to thepre-charge of each single VFD 340(a-n) due to each correspondingtransformer providing the electric power 355 at the auxiliary voltagelevel to each single VFD 340(a-n) as provided by the auxiliary systemtransformer 410 before exposing each single VFD 340(a-n) to the electricpower 360 at the power generation voltage level. Thus, any negativeimpact to the power generation system 310 after each single VFD 340(a-n)is exposed to the electric power 360 at the power generation voltagelevel is significantly decreased.

In an embodiment, the electric driven hydraulic fracking system 400 mayinclude a black start generator 405. The black start generator 405generates power and provides black start electric power 460 to thesingle VFDs 340(a-n) via the power distribution trailer 320 withouthaving to rely on the power generation system 310 to provide power tothe single VFDs 340(a-n). In doing so, the black start generator 405 mayprovide black start electric power 460 to the single VFDs 340(a-n) whilethe power generation system 310 is inactive such that the voltage levelof the black start electric power 460 is sufficient to thereby enablethe single VFDs 340(a-n) to operate, enable the transformers associatedwith the single VFDs 340(a-n) to pre-magnetize and pre-charge the singleVFDs 340(a-n), enable the VFD controllers 345(a-n) to operate thetrailer auxiliary systems 315(a-n), and/or enable any otherfunctionality related to the single VFDs 340(a-n) without having toactivate the power generation system 310 that will be apparent to thoseskilled in the relevant art(s) without departing from the spirit andscope of the disclosure. In an embodiment, the black start electricpower 460 may be at a voltage level that is substantially equivalent tothe voltage level of the electric power 355 provided by the auxiliarytransformer 410. For example, the black start electric power 460 may ata black start voltage level of 480V. The black start electric power 460may be at any voltage level that is sufficient to activate the singleVFDs 340(a-n) to operate in a decreased capacity as compared to when thesingle VFDs 340(a-n) are provided with the electric power 360 at thepower generation voltage level that will be apparent to those skilled inthe relevant art(s) without departing from the spirit and scope of thedisclosure.

As discussed in detail above, the auxiliary system transformer 410 mayprovide the electric power 355 at the auxiliary voltage level to eachsingle VFD 340(a-n) so that each single VFD 340(a-n), each transformerassociated with each single VFD 340(a-n), each VFD controller 345(a-n),the trailer auxiliary systems 315(a-n), and so on may operate asdiscussed in detail above. However, such operation based on the electricpower 355 at the auxiliary voltage level still requires that the powergeneration system 310 generate the electric power 350 at the powergeneration voltage level. In doing so, the power sources included in thepower generation system 310 are required to be activated and operatingat a capacity necessary to generate the electric power 350 at the powergeneration voltage level. Such an operation of the power sources togenerate the electric power 350 at the power generation voltage levelconsumes significant energy. However, such significant consumption ofenergy by the power sources of the power generation system 310 togenerate the electric power 350 at the power generation voltage levelmay be unnecessary when each single VFD 340(a-n) may simply require tooperate with the electric power 355 at the auxiliary voltage level.

For example, significant time may lapse before the fracking operation isto initiate in which the fracking equipment 370 is required to beactivated and to begin fracking the fluid from the well therebyrequiring the single shaft motors 150(a-n) to drive the single fluidpumps 160(a-n) in which the single VFDs 340(a-n) are required to providethe VFD voltage level of 4160V. During that lapse of significant time ofpreparation before the fracking operation, the single VFDs 340(a-n) maybe activated via the electric power 355 at the auxiliary voltage levelof 480V so that each single VFD 340(a-n), each transformer associatedwith each single VFD 340(a-n), each VFD controller 345(a-n), the trailerauxiliary systems 315(a-n), and so on may operate as discussed in detailabove. However, to do so, having the power generation system 310 consumeunnecessary energy to provide the electric power 355 at the auxiliaryvoltage level of 480V for such a significant amount of time beforegenerating the electric power 360 at the power generation voltage levelof 13.8 kV and/or 12.47 kV is unnecessary.

Rather, the black start generator 405 may provide the black startelectric power 460 to the single VFDs 340(a-n) via the powerdistribution trailer 320 such that the single VFDs 340(a-n), thetransformer associated with the single VFDs 340(a-n), the VFDcontrollers 345(a-n), the trailer auxiliary systems 315(a-n) and so onmay operate at a reduced capacity while still contributing to thepreparation of the fracking operation without requiring the activationof the power generation system 310. For example, the black startgenerator 405 may provide black start electric power 460 at the blackstart voltage level to each of the single VFDs 340(a-n) via the powerdistribution trailer 320 without having to activate the power generationsystem 310 to do so. In such an example, the back start electric power460 at the black start voltage level provided to the single VFDs340(a-n) via the power distribution trailer 320 may enable each of theVFD controllers 345(a-n) to be powered up as well as the ventilationsystems of the trailer auxiliary systems 315(a-n) may be activated. Thesingle VFDs 340(a-n) may pre-heat and feedback as to the status of thesingle VFDs 340(a-n) may be provided to the fracking control center 380via the VFD controllers 345(a-n) as to the status of the single VFDs340(a-n) during pre-charge.

In doing so, the power generation system 310 may idle as the single VFDs340(a-n) are preparing to arrive at a state to drive the single shaftelectric motors 150(a-n) to initiate the fracking operation. Activatingthe power generation system 310 from an idle state as the single VFDs340(a-n) prepare to arrive to a state to initiate the fracking operationis an unnecessary consumption of significant energy by the powergeneration system 310 when the black start generator 405 may provide theblack start electric power 460 that is sufficient to prepare the singleVFDs 340(a-n) to an operating state as well as during the preparationperiod to initiate the fracking operation while consuming significantlyless power than the power generation system 310.

The VFD controllers 345(a-n) may provide feedback to the frackingcontrol center 380 as to the status of the single VFDs 340(a-n) as theblack start generator 405 provides the black start electric power 460 tothe single VFDs 340(a-n) via the power distribution trailer 320. Thefracking control center 380 may also monitor the power generation system310 to determine when the power sources included in the power generationsystem 310 reach a status of being able to generate the electric power350 at the power generation voltage level. Once the fracking controlcenter 380 determines that the power generation system 310 has reached astatus to generate the electric power 350 at the power generationvoltage level, the fracking control center 380 may execute asynchronized transfer scheme to transfer the electric power provided bythe power distribution trailer 320 to the single VFDs 340(a-n) from theblack start electric power 460 provided by the black start generator 405to the electric power 350 at the power generation voltage level providedby the power generation system 310. The fracking control center 380 maythen deactivate the black start generator 405 such that the black startgenerator 405 no longer consumes unnecessary energy.

The power distribution trailer 320 may also provide additionalflexibility with regard to additional electric power that may begenerated from the electric power 350 at the power generation voltagelevel as generated by the power generation system 310 such that theadditional electric power is provided at additional voltage levels inaddition to the electric power 360 at the power generation voltage leveland the electric power 355 at the auxiliary voltage level. As mentionedabove, the hydraulic fracking system 400 may operate as an isolatedisland in that all electric power required to operate all aspects ofequipment required to execute the fracking operation may be providedfrom the power generation system 310 and then distributed by the powerdistribution trailer 320. In doing so, the power distribution trailer320 may customize the voltage levels of the electric power 350 at thepower generation voltage level generated by the power generation system310 to distribute the necessary electric power at the necessary voltagelevels to all aspects and/or equipment required for the execution of thefracking operation thereby not requiring additional power sources and/orpower generation systems.

In doing so, the switchgear transformer configuration 335 may include anadditional system transformer 420 that is in addition to the auxiliarysystem transformer 410. The additional system transformer 420 is atransformer included in the switchgear transformer configuration 335that provides electric power 450 at an additional voltage level thatdiffers from the electric power 355 at the auxiliary voltage level asprovided by the auxiliary transformer 410. The additional systemtransformer 420 may provide electric power 450 at additional voltagelevels that are higher than the auxiliary voltage level as well asadditional voltage levels that are lower than the auxiliary voltagelevel. As a result, the additional system transformer 420 may providethe electric power 450 at the additional voltage level to an additionalsystem 440 that requires electric power at a voltage level that differsfrom the electric power 355 at the auxiliary voltage level of 480V asprovided by the auxiliary system transformer 410. Thus, the additionalsystem transformer 420 may provide the electric power 450 at theadditional voltage level that is customized for the additional system440 such that the additional system 440 may also be powered by electricpower generated by the power generation system 310 and distributed bythe power distribution trailer 320.

For example, the additional system 440 may include a motor controlcenter for a blending operation required for the fracking operation. Insuch an example, the motor control center for the blending operation mayinclude four 500HP electric motors that require electric power 450 atthe additional voltage level of 4160V in order to drive the blendingequipment necessary to execute the blending operation during thefracking operation. The electric power 450 at the additional voltagelevel of 4160V differs from the electric power 360 at the powergeneration voltage level of 13.8 kV and/or 12.47 kV as provided by theswitchgear configuration 305 as well as differs from the electric power355 at the auxiliary voltage level of 480V as provided by the auxiliarysystem transformer 410. Rather, the additional system transformer 420provides additional customization to the electric power 450 provided atthe additional voltage level of 4160V such that the additional system440 that requires the customized electric power 450 provided at theadditional voltage level of 4160V in the motor control center for theblending operation may be distributed by the power distribution trailer320.

In another example, the additional system 440 may include a sitelighting system to provide light to the fracking site. In such anexample, the lighting system requires electric power 450 at theadditional voltage level of 120V in to provide to the lighting system toemit light to the fracking site. The electric power 450 at theadditional voltage level of 120V differs from the electric power 360 atthe power generation voltage level of 13.8 kV and/or 12.47 kV asprovided by the switchgear configuration 305 as well as differs from theelectric power 355 at the auxiliary voltage level of 480V as provided bythe auxiliary system transformer 410. Rather, the additional systemtransformer 420 provides additional customization to the electric power450 provided at the additional voltage level of 120V such that theadditional system 440 that requires the customized electric power 450provided at the additional voltage level of 120V in the lighting systemmay be distributed by the power distribution trailer 320. The additionaltransformer 420 may include any quantity of additional transformers inaddition to the auxiliary system transformer 410 and may provideelectric power 450 at any additional voltage level that is greater thanand/or less than the electric power 355 at the auxiliary voltage levelto provide such electric power as required by the any quantity ofadditional systems that will be apparent to those skilled in therelevant art(s) without departing from the spirit and scope of thedisclosure.

The power distribution trailer 320 includes the power distributiontrailer controller 430. The power distribution trailer controller 430 isthe onboard control system for the power distribution trailer 320. Thepower distribution trailer controller 430 may operate each of theauxiliary features of the power distribution trailer 320 such as the airflow of the power distribution trailer 320 to ensure that the equipmentpositioned on the power distribution trailer 320 is cooled andmaintained at a temperature that prevents damage to the equipmentpositioned on the power distribution trailer 320. In doing so, the powerdistribution trailer 320 may operate the auxiliary features of the powerdistribution trailer 320 in a similar manner as the VFD controllers345(a-n) operate the trailer auxiliary systems 315(a-n) of the pumptrailers 330(a-n).

The power distribution controller 430 may also centralize the data thatis generated by the components included in the electric driven hydraulicfracking system 400. As discussed in detail above, the powerdistribution trailer 320 distributes the electric power 350 at the powergeneration voltage level as generated by the power generation system 310and then distributes the electric power 360 at the power generationvoltage level and the electric power 355 at the auxiliary voltage levelto the single VFDs 340(a-n) that is then provided to the VFD controllers345(a-n) and the trailer auxiliary systems 315(a-n). The powerdistribution trailer 320 also distributes the electric power 355 at theauxiliary voltage level to the auxiliary systems 390. The powerdistribution trailer 320 also distributes the electric power 450 at theadditional voltage level. In doing so, the power distribution trailercontroller 430 communicates directly to each of the components includedin the electric driven hydraulic fracking system 400 and therebyoperates as a conduit of the communication of data generated by each ofthe components of the electric driven hydraulic fracking system 400 viacommunication link 365.

As a result, the power distribution controller 430 may act as a hub withregard to the data generated by the single VFDs 340(a-n), the VFDcontrollers 345(a-n), the trailer auxiliary systems 315(a-n), theadditional systems 440, the auxiliary systems 390, the fracking controlcenter 380, and/or the power generation system 310. As the single VFDs340(a-n), the VFD controllers 345(a-n), the trailer auxiliary systems315(a-n), the additional systems 440, the auxiliary systems 390, thefracking control center 380, and/or the power generation system 310operate and/or collect data and/or generate data, such data may bedistributed to the power distribution controller 430. The powerdistribution controller 430 may then distribute such data to the othercomponents and/or execute operations based on the data received fromeach of the components included in the electrical driven hydraulicfracking system 400.

As the single VFDs 340(a-n) operate and the single shaft electric motors150(a-n) drive the single hydraulic fluid pumps 160(a-n) to execute thefracking operation, the single VFDs 340(a-n) and the VFD controllers345(a-n) may communicate data as to the status of the numerousparameters of the single VFDs 340(a-n), the single shaft electric motors150(a-n) and the single hydraulic fluid pumps 160(a-n) as suchcomponents operate to execute the fracking operation to the powerdistribution controller 430. The power distribution controller 430 maythen operate as a conduit of such data and provide such data to thefracking control center 380 such that the fracking control center 380may determine any actions that may be required based on the currentstatus of such components via communication link 365.

For example, the fracking control center 380 requires that 100 barrelsper minute at 13000 PSI be driven by the fracking equipment 370. Thefracking control center 380 may then instruct the VFD controllers345(a-n) to ramp up the single VFDs 340(a-n) such that the single shaftelectric motors 150(a-n) may ramp up to drive the single hydraulic pumps160(a-n) to drive the fracking equipment 370 at 100 barrels per minuteat 13000 PSI. The VFD controllers 345(a-n) may then provide data withregard to the current state of the single VFDs 340(a-n), the trailerauxiliary systems 315(a-n), the single shaft electric motors 150(a-n),the single hydraulic pumps 160(a-n) and so on with regard to the statusof each component in real-time to the power distribution trailercontroller 430. The power distribution trailer controller 430 may thenoperate as a conduit of such data to the fracking control center 380such that the fracking control center 380 may monitor the status of eachcomponent in real-time based on the data provided by the powerdistribution trailer controller 430 to determine if any actions that maybe required based on the current status of such components.

In another example, the power distribution trailer controller 430 maymonitor the operation of the power sources included in the powergeneration system 310 to determine whether the electric power generated350 at the power generation voltage level is sufficient for the singleVFDs 340(-n) to drive the single shaft electric motors 150(a-n) to drivethe single hydraulic pumps 160(a-n). In such an example, the powergeneration system 310 may include several gas turbine engines. The powerdistribution controller 430 may determine that the status of one of thegas turbine engines is signaling that the gas turbine engine is failing.In doing so, the fracking control center 380 may execute a load sharingto share the load of the failed gas turbine engine with the remainingactive gas turbine engines to maintain the fracking operation. The powerdistribution trailer controller 430 may determine the load sharing ofthe gas turbine engines as provided by the fracking control center 380.

In doing so, the power distribution trailer controller 430 may determinethe MW of electric power 350 being generated by the remaining gasturbine engines which is less than the MW of electric power 350generated when each of the gas turbine engines were operational. Thepower distribution trailer controller 430 may then determine the amountof MW being consumed by the single VFDs 340(a-n) to drive the singleshaft electric motors 150(a-n) and the single hydraulic pumps 160(a-n)in executing the fracking operation. The power distribution controller430 may then instruct the VFD controllers 345(a-n) to fade back thesingle VFDs 340(a-n) such that the single VFDs 340(a-n) consume the MWof electric power 360 as available from the remaining gas turbineengines to avoid a brown out and/or black out of the power generationsystem. In doing so, the fracking operation may continue uninterrupteddespite a gas turbine engine failing.

Thus, the power distribution trailer controller 430 may act as theconduit as well as monitor each of the single VFDs 340(a-n), the VFDcontrollers 345(a-n), the trailer auxiliary systems 315(a-n), theadditional systems 440, the auxiliary systems 390, the fracking controlcenter 380, and/or the power generation system 310. As the single VFDs340(a-n), the VFD controllers 345(a-n), the trailer auxiliary systems315(a-n), the additional systems 440, the auxiliary systems 390, thefracking control center 380, and/or the power generation system 310operate and/or collect data and/or generate data, such data may bedistributed to the power distribution controller 430 via communicationlink 365.

FIG. 5 illustrates a block diagram of an of an electric driven hydraulicfracking system 500 that further describes the incorporation of thepower distribution trailer into the electric driven hydraulic frackingsystem 500. The power distribution trailer includes a bus A 510, a bus B520, a plurality of feeders 530(a-n), where n is equal to the quantityof VFD connections 550(a-n). The approach in how the electric power 350at the power generation voltage level is distributed by the switch gearconfiguration 305, the auxiliary system transformer 410, and/or theblack start generator 405 to the single VFDs 340(a-n) is discussed inmore detail below. The electric driven hydraulic fracking system 500shares many similar features with the hydraulic fracking operation 100,the single pump configuration 200, the electric driven hydraulicfracking system 300, and the electric driven hydraulic fracking system400; therefore, only the differences between the electric drivenhydraulic fracking system 500 and the hydraulic fracking operation 100,the single pump configuration 200, the electric driven hydraulicfracking system 300, and the electric driven hydraulic fracking system400 are to be discussed in further detail.

The power generation trailer 320 includes bus A 510 and bus B 520. Bus A510 may operate as an electric bus such that bus A 510 may propagate theelectric power 355 at the auxiliary voltage level. In doing so, bus A510 may be electrically connected to any component included in the powerdistribution trailer 320 that provides the electric power 355 at theauxiliary voltage level. For example, bus A 510 may be electricallyconnected to the auxiliary system transformer 410 and/or the black startgenerator 405 such that the auxiliary system transformer 410 and/or theblack start generator 405 provides the electric power 355 at theauxiliary voltage level. Bus B 520 may operate as an electric bus suchthat bus B 520 may propagate the electric power 360 at the powergeneration voltage level. In doing so, bus B 520 may be electricallyconnected to any component included in the power distribution trailer320 that provides the electric power 360 at the auxiliary voltage level.For example, bus B 520 may be electrically connected to the switchgearconfiguration 305 such that the switchgear configuration provides theelectric power 360 at the power generation voltage level.

Bus A 510 enables the different components included in the powerdistribution trailer 320 that provide the electric power 355 at theauxiliary voltage level, such as the auxiliary system transformer 410and/or the black start generator 405, to easily distribute the electricpower 355 at the auxiliary voltage level to each of the feeders530(a-n). For example, the auxiliary system transformer 410 and/or theblack start generator 405 may simply provide the electric power 355 atthe auxiliary voltage level to Bus A 510 and then bus A 510 propagatesthe electric power 355 at the auxiliary voltage level to each of thefeeders 530(a-n). Rather than have the auxiliary system transformer 510and/or the black start generator 405 electrically connect to each of thedifferent feeders 530(a-n) individually requiring significantly morecabling, the auxiliary system transformer 510 and/or the black startgenerator 505 may simply electrically connect to bus A 510 and then busA 510 may propagate the electric power 355 at the auxiliary voltagelevel to each of the feeders 530(a-n).

Bus B 520 enables the different components included in the powerdistribution trailer 320 that provide the electric power 360 at thepower generation voltage level, such as the switchgear configuration305, to easily distribute the electric power 360 at the power generationvoltage level to each of the feeders 530(a-n). For example, theswitchgear configuration 305 may simply provide the electric power 360at the power generation voltage level to Bus B 520 and then bus B 520propagates the electric power 360 at the power generation voltage levelto each of the feeders 530(a-n). Rather than have the switchgearconfiguration 305 electrically connect to each of the different feeders530(a-n) individually requiring significantly more cabling, theswitchgear configuration 305 may simply electrically connect to bus B520 and then bus B 520 may propagate the electric power 360 at the powergeneration voltage level to each of the feeders 530(a-n).

Each of the feeders 530(a-n) may provide the connections and include theappropriate relays and/or contacts to propagate the electric power 360at the power generation voltage level as propagated from bus B 520, theelectric power 355, 460 at the auxiliary voltage level as propagatedfrom bus A 510, and the communication link 365 to the each of the singleVFDs 340(a-n). The condensing of the electric power 360 at the powergeneration voltage level, the electric power 355, 460 at the auxiliaryvoltage level, and the communication link 365 into a correspondingsingle feeder 530(a-n) for each corresponding single VFD 340(a-n)enables the electric power 360, the electric power 355, 460, and thecommunication link 365 to be consolidated into a corresponding singlecable 540(a-n). Rather than have numerous cables running from the powerdistribution trailer 320 to each of the different single VFDs 340(a-n)such that each of the electric power 360, the electric power 355, 460,and the communication link 365 is included in its own individual cable,each of the feeders 530(a-n) may consolidate the electric power 360, theelectric power 355, 460, and the communication link 365 into a singlecorresponding cable 540(a-n) thereby significantly reducing the amountof cables required to be ran between the power distribution trailer 320and each corresponding single VFD 340(a-n). Each of the cables 540(a-n)may then electrically connect the electric power 360, the electric power355, 460, and the communication link 365 to each corresponding singleVFD 340(a-n) via the VFD connection 550(a-n) associated with each singleVFD 340(a-n).

The communication link 365 as included in the cables 540(a-n) mayprovide communication from the VFD connection 550(a-n) to thecorresponding feeder 530(a-n) and then to the power distribution trailercontroller 430. The communication link 365 may enable the powerdistribution trailer controller 430 to determine whether the appropriateelectric power 360 at the voltage level of 13.8 kV and the appropriateelectric power 355 at the auxiliary level of 480V is connected from theappropriate feeder 530(a-n) to the appropriate VFD connection 550(a-n).Often times, installers of the electrical electric driven hydraulicfracking system 500 may incorrectly connect cables 540(a-n) such thatthe incorrect VFD connection 550(a-n) is connected to the incorrectfeeder 530(a-n). In doing so, the incorrect electric power 360 at thepower generation voltage level and/or the incorrect electric power 355at the auxiliary voltage level may be connected to the incorrect singleVFD 340(a-n).

For example, the installer in the confusion of installing the electricdriven hydraulic fracking system 500 may incorrect connect cable 540 afrom feeder 530 a to VFD connection 550 n. In doing so, the installerconnected the incorrect electric power 360 at the power generationvoltage level of 13.8 kV and/or the incorrect electric power 355 at theauxiliary voltage level of 480V to the incorrect single VFD 340 n viaVFD connection 550 n. Rather than relying on manual policy and procedurefor the installers to verify whether each cable 540(a-n) correctlyconnects each VFD connection 550(a-n) to each corresponding feeder530(a-n), the power distribution trailer controller 430 may poll eachfeeder 530(a-n) and to thereby determine whether each feeder 530(a-n) isconnected to the appropriate VFD connection 550(a-n) via the appropriatecable 540(a-n) via the communication link 365 included in each cable540(a-n). In doing so, the power distribution trailer controller 430 mayverify whether each feeder 530(a-n) is connected to the appropriate VFDconnection 550(a-n) based on the polling via the communication link 365included in each cable 540(a-n). The power distribution trailercontroller 430 may then confirm that each feeder 530(a-n) is connectedto each appropriate VFD connection 550(a-n) when each communication link365 confirms based on the polling of the power distribution trailercontroller 430. The power distribution trailer controller may thengenerate an alert and identify each feeder 530(a-n) that is connected tothe incorrect VFD connection 550(a-n) when the communication link 365identifies the incorrect connection based on the polling of the powerdistribution trailer controller 430.

As noted above, medium voltage cables may propagate the AC voltagesignal 360 at the voltage level of 13.8 kV from the power distributiontrailer 320 to each of the VFDs 340(a-n). Low voltage cables maypropagate the auxiliary voltage signal 355 at the auxiliary voltagelevel of 480V from the power distribution trailer 320 to each of theVFDs 340(a-n). Communication cables may propagate communication signals365 from the power distribution trailer 320 to each of the VFDs340(a-n). FIG. 6 illustrates a top-elevational view of connectorconfiguration for each of the VFDs 340(a-n) that may couple to a mediumvoltage cable, a low voltage cable, and a communication cable.

The connector configuration 600 includes medium voltage connectors610(a-b) with each including a medium voltage plug and receptacle toeliminate the need of skilled personnel to connect the medium voltagecables to the VFDs 340(a-n) using hand tools and being thereby exposedto the conductors. Rather than using manual terminations with delicatetermination kits, the medium voltage connections 610(a-b) with plugsenable medium voltage cables to be easily connected to the VFDs 340(a-n)to propagate the AC voltage signal 360 at the power generation voltagelevel without any risk of shorts and/or nicks in the cable. The mediumvoltage connections 610(a-b) include lockable provisions that preventunauthorized connection or disconnection of the medium voltage cables tothe medium voltage connections 610(a-b) and provide lock out tag outfeatures for safe working on system components. The low voltageconnections 620(a-b) provide connections to the low voltage cables thatpropagate the auxiliary voltage signal 355 at the auxiliary voltagelevel of 480V to the VFDs 340(a-n). The communication connection 630provides a connection to the communication cable to propagatecommunication signals 365 to the VFDs 340(a-n).
